.SH NAME
libkrb5 \- MIT Kerberos 5 library
.SH SYNOPSIS

\fBcc\fR \fB-I/usr/include/kerberosv5\fR [ \fIflag\fR... ] \fIfile\fR... \fB-lkrb5\fR [ \fIlibrary\fR...]

.SH DESCRIPTION
.LP
The functions in this library are the routines that comprise the MIT Kerberos 5
library.
.SH INTERFACES
.LP
The shared object \fBlibkrb5.so\fR provides the public interface defined below.
.sp
.LP
The \fBkrb5\fR library is provided as a convenience to allow native \fBkrb5\fR
applications to be built and to run. Compatibility between Solaris releases of
the \fBkrb5\fR interface is not guaranteed. For new applications that require
these features, \fBlibgss\fR(3LIB) is recommended.
.sp
.LP
For detailed documentation on the \fBkrb5\fR interface, see the MIT Kerberos 5
web site at \fBhttp://web.mit.edu/kerberos\fR.
.sp
.LP
The \fBkrb5_cc_gen_new\fR routine, listed in \fBkrb5.h\fR section, is flawed
and should be avoided. Until a new routine is available from MIT, the following
can be done:
.sp
.in +2
.nf
char ccname[40];
int tmpfd;

snprintf(ccname,sizeof(ccname),"FILE:/tmp/krb5cc_%d_XXXXXX",
        geteuid());

if ((tmpfd = mkstemp(ccname+strlen("FILE:")))==-1) {
        log("mkstemp(): %.100s", strerror(errno));
        problem = errno;
        goto fail;
}
if (fchmod(tmpfd,S_IRUSR | S_IWUSR) == -1) {
        log("fchmod(): %.100s", strerror(errno));
        close(tmpfd);
        problem = errno;
        goto fail;
}
 close(tmpfd);
problem = krb5_cc_resolve(authctxt->krb5_ctx, ccname, &ccache);
\&...
fail:
.fi
.in -2

.sp
.LP
The \fBkrb5_string_to_key\fR and \fBkrb5_string_to_key\fR routines, listed in
\fBkrb5.h\fR section, are part of the old cryptosystem and should not be used
in new apps.
